Best Practices for Multi-Language Websites

Overview

A comprehensive multi-language implementation involves three aspects:

• Interface translation
• Content translation
• URL routing

Options for URL Translation

There are two main approaches to URL translation:

Query-Based Routing:

• URL format: http://site.tld/[:query]
• Language is determined from the query segment.
• Resolves routing conflicts using additional language sources (e.g., cookies, HTTP headers).
• Can be challenging to determine language when multiple translations exist for query segments.

Language-Based Routing:

• URL format: http://site.tld/[:language]/[:query]
• Language is specified in the URL path.
• Simplifies language determination and query translation.
• Requires careful attention to routing patterns and default language handling.

Factors to Consider

• Transliteration vs. IDN: Use transliteration to avoid compatibility issues with non-ASCII characters.
• Fallback Mechanisms: Handle missing translations by using default values or regenerating translation files.
• SEO Impact: URL structure can affect search engine optimization.

Implementing in Laravel

While Laravel does not support multilingual routing out of the box, it can be extended through:

• Custom Routing Classes: Override or extend the core routing class to implement language-based routing.
• Middleware: Apply language detection middleware to determine the language and set it as a request attribute.

Handling Content

• Database-Driven: Store translations in a database with a structure like Controller.View.parameter.
• File-Based: Generate translation files (e.g., .ini) for each language and dynamically load them based on the language detected.
• Content Caching: Improve performance by caching translated content and automatically updating the cache when translations change.

Recommendation

The preferred approach for URL translation is language-based routing. It provides a clear separation between language and content, simplifies translation handling, and improves search engine visibility.
